METAL BENDING MACHINE. APPLICATION FILED MAR. 21, I916.

HERMAN BUSSEL, OF EL PASO, TEXAS.

IVIE'IAL-BENDING MACHINE.

Specification of Letters Patent.

Patented Dec. 12, 1916.

Application filed March 27, 1916. Serial No. 87,037.

To all whom it may concern Be it known that I, HERMAN Bussnn, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Metal-Bending Machines; of which the following'is a specification, reference being had to the accompanying drawings.

This invention relates to an improved metal bending and shearing machine, and has for its primary object to provide a simple and easily operated mechanism whereby a metal bar may be readily bent to any desired angle.

It is a more particular object of the invention to provide a machine for the above purpose including a suitable base, standards rotatably mounted upon the base and arranged in juxtaposition to each other, each of said standards being slotted to receive the metal bar, the bar being adapted to be arranged in one of the standards whereby, when said standard is rotated, the bar bearing against the other standard is angularly bent.

It is a further general object of the invention to provide a machine for the above purpose, embodying but few parts which are simple and durable in construction and capable of being easily and quickly assembled in operative position.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts to be'hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a perspective view illustrating a metal bar arranged in position upon the machine to be bent; Fig. 2 is a top plan view showing the bar after it has been bent in the operation of the machine; Fig. 3 is a vertical sectional View taken on the line 8-8 of Fig. 2; Fig. 4 is a perspective view of one of the slotted posts or standards; and Fig. 5 is a detail perspective view of the rectangular bending sleeve.

Referring in detail to the drawings, 5 designates the heavy, cast metal base, preferably, though not necessarily, of the form shown in Fig. 2. This metal base is pro vided in its approximate center with a vertically extending, rectangular opening 6 which tapers from its upper to its lower end, This opening 6 is adapted to be (118* posed in registering relation over a socket in an anvil or other suitable support, and the anchoring pin or wedge 7 is driven through the opening and into the socket. In the major portion of the base 5, a multiplicity of relatively small, equidistantly spaced, vertical openings 8 are formed for a purpose to be hereinafter referred to.

9 and 10, respectively, designate post receiving openings extending vertically through the base 5. Each of these openings is diametrically enlarged adjacent its upper end to provide an annular shoulder 11 therein.

12 and 13 indicate the metal bending posts or standards which are of relatively different diameters and are provided upon one of their ends with reduced, cylindrical studs or extensions 14: and 15 respectively, for engagement in the openings 9 and 10 of the base 5. The body portions of the standards 12 and 13, at their juncture with the reduced studs, are of such diameter as to fit snugly within the enlarged upper end portions of the openings 9 and 10 and rest upon the shoulders 11. The metal bending posts or standards areidentical in construction, and the description of one will, therefore, suflice for both. Each standard is provided in its body portion with a longitudinally extending slot 16 which divides said body into spaced, parallel arms 17, each of which, at its upper end, has its outer peripheral face slightly beveled or tapered, as clearly shown in Fig. 3 of the drawings. One of-the arms 17 is provided with a series of spaced, threaded openings 18. The pivot studs on the lower ends of the standards which turn in the openings provided in the base, are of such length as to project slightly below the base 5. Upon these projecting ends of the pivot studs, collars or washers 19 are fitted and securely held in place by means of set screws 20, whereby the standards are held against upward movement with respect to the base, and detachably retained in connection therewith.

A metal sleeve 21 is provided for each of the standards 12 and 13 and is adapted to fit snugly thereover. By beveling the outer faces of the arms 17 of the standards as above explained, these sleeves may be easily and quickly slipped downwardly over the standards. In Fig. 5 I have shown a rectangular sleeve 22 which may be employed When it is de ired to ma e a Square bend in 'ends of the arms the metal bar. One side of this sleeve is adapted to be fitted into the vertical slot 16 of one of the posts or standards, one of the arms 17 projecting through said sleeve. In the other side wall of the sleeve, a screw 23. is threaded, which is adapted to be engaged in any one of the threaded openings 18 so as to hold the sleeve in place against vertical movement. Only one of these sleeves is necessary and is adapted to be fitted upon the larger of the posts or standards 12.

24 designates an operating lever which is provided with an annular head 25 on one end, said annular head being of frusto-conical form and having a central, diametrically eX- tending web or bar 26. This web is adapted to be received in the vertical slot 16 of either of the standards 12 or 13. The lever head 25 is fitted upon the upper tapering 17 of the standard, the beveled or inclined peripheral faces of said arms binding against the longitudinally tapering inner wall of the annular head.

As clearly shown in Figs. 1 and 2 of the drawings, when it is desired to form an angular bend in a metal bar, the bar, after being suitably heated, is inserted edgewise downwardly into the vertical slot 16 of one of the rotatable standards. The metal sleeve 21 is fitted upon the other adjacent standard, and the bar extends horizontally against one side of this sleeve. A set screw such as indicated at 27, may now be engaged in any one of the openings 18 and adjusted into tight binding engagement with the metal bar to hold the same against longitudinal shifting movement on the standard. The operating lever is then applied to the upper end of this standard and the said standard then turned or rotated upon the base in a direction toward that portion of the bar which bears against the metal sleeve 21 on the otherstandard. It will thus be obvious that the bar will be bent in the manner shown in Fig. 2. iVhen it is desired to in sure the bending of the bar so that the two portions thereof will extend at angles of 90 with respect to each other, the rectangular sleeve 22 is fitted into the slot of the standard 12in which the bar is arranged. The

sleeve is of considerably less thickness than the width of the slot, so that both the sleeve and the metal bar may be readily engaged therein. 7

It is understood, of course, that the metal bar bears against one side of the other stand- Oopies of this patent may be obtained for five cents each, by addressing the ard 13 so that when the standard 12 is rotated, the bar will be bent around one end of the sleeve 22 and in contact with the face thereof so that the two portions of the bar will extend at right angles to each other.

From the foregoing description, taken in connection with the accompanying drawings, it is believed that the construction,

manner of operation and several advantages of my improved metal bending machine will be clearly and fully understood. The apparatus has been found highly satisfactory for all ordinary metal bending operations and is especially designed for use by blacksmiths, wheelwrights, and similar mechanics, as it enables the operator to expeditiously perform the various metal bending operations which are frequently required. The machine being of such simple construction may also be manufactured and sold at relatively small cost. It is apparent that the machine can be constructed in various sizes and a number of the metal bending posts or standards may be provided having bar receiving slots varying in width so that metal bars of different thicknesses may be readily applied thereto and properly bent.

lVhile I have shown and described the preferred construction and operation of the several parts of the device, it is to be understood that the same is susceptible of considerable modification therein and I, therefore, reserve the privilege of adopting all such legitimate modifications as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is In a metal bending apparatus, a base, spaced rotatable posts removably mounted upon said base, each of said posts having a longitudinal slot opening upon the upper HERMAN BUSSEL.
